I has Vessel View installed, the dealer did not get it right, and later found out some parts were missed. After being charged full retail for the " missed parts " I have decided to finish it myself.
I wanted Cruise control, but my boat had DTMS ( digital throttle, mechanical Shift ).. The dealer sold me the extra module for this, and I installed it, deep in the instructions ( which I lost ) It made note of a Can_X cable needed, not a CanBus. IT has to run from the module that's under the dash, back to the engine. These are available in different lengths.

I was hoping someone had these part numbers and could help me figure out what one need.

Any help would be appreciated.
